District 9 as the world's nations argued over what to do with them. Now, patience over the alien situation has run out. Control over the aliens has been contracted out to Multi-National United (MNU), a private company uninterested in the aliens' welfare - they will receive tremendous profits if they can make the aliens' awesome weaponry work. So far, they have failed; activation of the weaponry requires alien DNA. The tension between the aliens and the humans comes to a head when an MNU field operative, Wikus van der Merwe (Sharlto Copley), contracts a mysterious virus that begins changing his DNA. Wikus quickly becomes the most hunted man in the world, as well as the most valuable - he is the key to unlocking the secrets of alien technology. Ostracized and friendless, there is only one place left for him to hide: District 9.
